Likewise, even though there were no significant changes in neutrophils when we compared the pre-infection time point to AHI time points, we observed positive correlations between hyperacute neutrophil counts and IP-10 (rho = 0.74, P = 0.006) (Supplementary figure 5B), neutrophils and IL-8 (rho = 0.58, P = 0.048) (Supplementary figure 5C), and neutrophils and BAFF (rho = 0.67, P = 0.033) (Supplementary figure 5D), suggesting that neutrophils could be secreting some of the cytokines. Here, TNFSF13B is linked to infection.
